This undated photo provided by General Motors shows a Chevy SS. For the first time in nearly two decades, the Chevrolet brand will have a rear-wheel-drive sedan in its U.S. lineup. General Motors Co. said Thursday, May 17, 2012, that the 2014 Chevrolet SS will go on sale in limited numbers late next year. The V-8-powered SS will be closely related to GM's Holden VF Commodore, a rear-wheel-drive sedan that will be sold in Australia. The new SS will also be Chevrolet's NASCAR Sprint Cup contender. It will debut in its race configuration at the 2013 Daytona 500. (AP Photo/GM)
